Train better with the award-winning Sports Tracker app. Your phone becomes a full-featured GPS sports computer, keeping track of everything from calories burned while running to your average cycling speed over altitude. You get maps, time and distance calculators, step count, and even heart rate when you use a compatible HR belt. All data is stored in a diary so you can chart your progress, find your strengths and weaknesses, and share with others. Millions of downloads worldwide —join the team.

What is Sportstracker?

"GPS based activity tracker and training diary

Nokia Sports Tracker lets you keep a diary of your workouts and training sessions and automatically stores information such as speed, distance and time, meaning you can easily monitor and analyse your progress. You can also choose to share your workouts with other Nokia Sports Tracker users and access theirs too - so you can train together, provide encouragement and get new ideas.

But you do not have to be sporty to enjoy Nokia Sports Tracker. You can use it to document your journeys by taking photos and videos, as well as to save your favourite routes and playlists. Simply upload the information to your personal widget for future reference.

Nokia Sports Tracker runs on Nokia S60 5.x devices. If your device does not have an integrated GPS, you can use Nokia Sports Tracker by connecting it to an external GPS module."

there is a site, where you can share and track your sport activities:

this new version of Sportstracker seems to be only for S60 5th Edition phones, like the new Nokia X6
